South African Pension Lump Sums and UK Tax

Update note (May 2026): This article has been updated to clarify that UK tax treatment of South African pension lump sums is fact-specific. In particular, the 25% tax-free treatment will not generally apply where the individual is under the relevant UK pension access age. In addition, where rights had accrued in the pension before 6 April 2017, it may be possible to take into account the value of those rights as at 5 April 2017 when calculating the UK taxable amount.

If you’re living in the UK and planning to take a lump sum from your South African pension fund, there are a few key facts you need to understand - especially around how the payment is taxed, and where.

Which Country Has Taxing Rights?

The UK–South Africa Double Taxation Convention (DTC) provides that the UK has taxing rights over pension income, including certain lump sums, where the recipient is UK tax resident at the time the payment is received.

In practice, HMRC will generally seek to tax the full amount of the lump sum in the UK and will not give credit for South African tax where the treaty allocates taxing rights to the UK.

However, in practice, SARS will still deduct tax at source using their standard lump sum withdrawal tables. There’s no exemption process unless you secure a 0% directive, which is very difficult to obtain once you’re no longer South African tax resident.

So what happens? In practice, this can result in South African tax being deducted at source, while the lump sum is also reported and taxed in the UK. Where South Africa has withheld tax in circumstances where the treaty allocates taxing rights to the UK, the appropriate route is to seek a refund from SARS.

UK Tax Treatment

If you are UK tax resident when you receive a lump sum from a South African pension fund, the payment must be considered for UK tax purposes and should be reported correctly on your UK Self Assessment tax return.

The UK tax treatment is not always simply that 75% of the lump sum is taxable. The position depends on the nature of the pension, the terms of the scheme, your age at the time of withdrawal, whether pension rights had accrued before 6 April 2017, and whether any UK tax relief was previously claimed on contributions.

In some cases, a 25% tax-free element may be available, but this is generally linked to UK pension access rules and will not necessarily apply where the individual was below the relevant UK pension access age at the time of withdrawal.

Separately, where rights had accrued in the pension before 6 April 2017, it may be possible to take into account the value of those rights as at 5 April 2017 when calculating the taxable amount in the UK. This can materially affect the UK tax outcome, but the treatment is fact-specific and should be reviewed carefully before the return is filed.

For this reason, the taxable amount should be calculated on a case-by-case basis rather than assuming that 75% of the lump sum is always taxable.

Did You Claim UK Tax Relief on the Contributions?

Here’s where things get more nuanced.

If the lump sum is treated as a flexible access payment for UK pension purposes, it may trigger the Money Purchase Annual Allowance (MPAA). This can restrict future money purchase pension contributions qualifying for tax relief to £10,000 per year.

HMRC’s current rates confirm the MPAA is £10,000 for 2025/26 and 2026/27.

This can affect your long-term retirement planning - especially if you continue to contribute to UK pensions.

Whether the MPAA applies depends on how the payment is treated for UK pension purposes and should be reviewed where the individual continues, or intends, to make UK pension contributions. In both cases, the lump sum must still be reviewed for UK tax purposes. The taxable amount will depend on the facts, including age, pre-6 April 2017 rights, scheme terms, and whether UK tax relief was previously claimed. The difference is whether it affects your ability to contribute tax-efficiently to UK pensions going forward.

What You Need to Do

Before withdrawing, or as soon as possible after receiving a South African pension lump sum, you should:

• Confirm your UK and South African tax residence position at the date of receipt.

• Obtain documentation showing the gross lump sum, South African PAYE deducted, and the fund type.

• Ask the pension provider for the value of your accrued pension rights as at, or as close as possible to, 5 April 2017.

• Review whether any UK tax relief was previously claimed on contributions.

• Report the lump sum correctly on your UK Self Assessment tax return, after assessing any available reliefs or deductions.

• Consider whether a SARS refund claim is available where South African tax has been deducted despite the treaty position.

• Take advice before filing, as the UK treatment can vary materially depending on the facts.

Because the UK treatment is highly fact-specific, we recommend obtaining advice before submitting your UK Self Assessment return or before approaching SARS for a refund. An incorrect assumption - particularly around the 25% tax-free element or pre-2017 rights - can lead to overpayment, under-reporting, or unnecessary HMRC/SARS correspondence.
